Very strong rotating storm system circulating around most of southern Ontario spawning various vicious cells. I was caught in one in Hamilton while on Centennial Parkway going towards the QEW where police had blocked off a lane of that road because a manhole cover had poppled off due to excessive rain. Very strong winds and lightning, torrential downpours in Hamilton. Light rain / thunder in north end St. Catharines. This tornadic system produced multiple tornados in other areas of the province today.
